I don't wish to sound rude, but I have children and one is a 12 year old who is a member of this site. It is true that some prime time programming has questionable language, but these programs are always marked with various warnings and, of course the well known "PG-13, etc, and not all pre-teens watch these programs. On this web site, and it is a great place for anyone who models, there are no warnings on posts, it wouldn't be feasible to even try. The printed word is much stronger than the spoken word. This is another thing to take into consideration.
I'm not naive, I know children hear bad language at school, on the telly, and other places, but that doesn’t make it right. Bad language isn't allowed in my house and such language shouldn’t be re-enforced on what I feel is a family oriented web site. So, I agree with Greg. I don't see a need in using a vulgar word to make a point.
